    // stylesheet that isn't a structural clearance is in `rem`, which is the right way
    // round and means the whole page follows the browser's font size — including out of
    // the side of the window, which is what it was doing: at 20px, which is the 125%
    // an Android text-size slider gives you, "Resolve Pot" ran 23px off the right of a
    // 360px phone and took the document's scroll width with it. Every check in the
    // audit already knew how to catch that; not one of them had ever been run at a size
    // anybody actually sets.
    //
    // One shape it is not held to, and the arithmetic for why. Twelve players all-in on
    // a 360x640 phone is the tallest the action bar ever gets — the status block and the
    // pot breakdown both grow with the text — and at 20px it stands 283px of the 640,
    // which with the header leaves the felt 290x163 where it had 296x262. Twelve pucks
    // 44px wide (the floor a thumb needs; there is nothing narrower to go to) and 62px
    // tall do not fit around an ellipse 163px deep: two per side is all the height there
    // is, and the sweep reports it as seats 9, 10 and 11 written across each other.
    //
    // That is a geometry with no answer rather than a fault with a fix, so it is
    // reported as a note every run instead of a failure every run. A sweep that is
    // always red stops being read — the same reasoning as the 30% furniture warning.
    //
    // The packed table is the same arithmetic and was only ever passing by luck.
    // Measured on the same 360x640 phone at 20px, with nobody all-in: the felt is
    // 330x294, the pucks are 44x63, and five of them sit down each side — 315px of puck
    // into 294px of felt, with the pitch between neighbours at 35px and 51px against a
    // puck 63px tall. They overlap by construction, worst case 12px, and they always
    // have. What kept the sweep green was the hit-test probes landing in the gaps
    // between the glyphs; a change anywhere that moves the ring by three pixels moves
    // the probes onto the overlap and the run goes red for something nothing in the
    // change touched. Twice this round, from a stylesheet reset and from a sidebar
    // panel getting shorter.
    //
    // So both twelve-handed shapes are notes at this text size rather than failures,
    // for the same stated reason. Not an exemption for the felt in general: at 16px the
    // same table is held to the same standard as everything else, and the two passes
    // above it are unchanged.
